Understand that during translation, the mRNA sequence is read in groups of nucleotides called codons.
Recall that each codon consists of a specific number of nucleotides that correspond to one amino acid.
Know that the genetic code is based on triplets, meaning each codon is made up of 3 nucleotides.
Recognize that these 3-nucleotide codons are translated by the ribosome to add one amino acid to the growing polypeptide chain.
Therefore, the number of nucleotides in mRNA that code for a single amino acid is 3.
